I found these exquisite melody and words for Saints Day in the Anglican hymnal of 1931.
Orlando Gibbons (1583 – 1625) composed the melody, known as Song 67.
Orlando was an English composer, virginalist and organist of the late Tudor and early Jacobean periods. He was a leading composer in the England of his day.
Glenn Gould revered him as THE composer alongside Bach.
Isaac Watts (1674-1748) wrote the beautiful words
Being a Nonconformist, Watts could not attend Oxford or Cambridge, He went to the Dissenting Academy at Stoke Newington in 1690. Much of the remainder of his life centred around that village, which is now part of Inner London.
